ABSTRACT:
The specification discloses a food packaging machine including a continuous conveyor which passes a plurality of filling and packaging stations. A plurality of die housings are connected to the conveyor. Two upstanding retaining projections are spaced apart in the bottom of each of the die housings. A pair of die fillers are dimensioned to be retained in each of the die housings and each includes an upper cavity for receiving a food product to be packaged. A rigid plate is disposed over a recess in the bottom of each of the die fillers and includes a keyhole-shaped aperture therein. A first portion of the aperture is dimensioned to receive one of the retaining projections when the die filler is positioned in a die housing. A second portion of the aperture is narrower than the first portion in order to receive the retaining projection when the die filler is slid relative to the die housing, in order to lock the die filler to the retaining projection. A spacer member fits between each of the die fillers in each of the die housings. The improved die filler connection prevents damage to the packaging machine during operation due to disengagement of the die filler from the die housing. Moreover, the present die filler connection enables faster changeover of die fillers in order to enable packaging of different sizes and shapes of food products.
